The SEC said Adams ran afoul of rules designed to make sure auditors are objective and impartial after he accepted tens of thousands of dollars in "casino markers'' at the same time he was serving as an advisor on the audit of a casino gaming corporation.

Casino markers are used by gambling customers to receive gaming chips drawn against their lines of credit at a casino.

SEC rules generally require auditors to refrain from conduct that could impede their independence as objective watchdogs, such as owning the stock of a client company or offering non-audit services to an audit client.

In this case, the SEC said Adams opened a line of credit at a casino that was run by an audit client, and that he concealed his casino markers from Deloitte and another Deloitte partner.

"The transactions by which Adams accepted the casino markers were loans from an audit client that are prohibited by the auditor independence rules,'' said Scott Friestad, an associate director in the SEC's enforcement division.

"Auditor independence is critical to the integrity of the financial reporting process,'' Friestad said. "Through his extensive use of casino markers, Adams clearly violated the rules and put his own desires ahead of his client's interests.''
